ADJUSTMENT FOR TEBMINALS WITHIN HEADS To all whom t may 10W/06m;

it known`v that I, EDWAnnA. ROBINSON, a citizen of the United States,re-sidinget "lontreal, Province of Quebec, Can-ada, have 4'iiventedacertain new and useful Adjustfient for Terminals Within Connecter leads,of which the following is a specificanon. My invention relates to trainconnecters intended for automatic operation to join air or steam,pipes.of adjacent cars.

The4 purpose of my inventionis to provide quick,l ready and reliablemeans Jfor determining thecxtent of normal projectionof train pipeyterminals beyond the connecter head by which they are carried.

A further purpose is toadjust the total extent. of projection of a trainpipe terminal byrboltsor lstuds extending parallel to the axesof Athetrain pipe terminals and surrounded individually, or collectively, foreach terminal by springs with springs about the terminals inside thebolts in the latter case.

.Furtlienpurposes will appearin the specification an in the claims.

I T.prefer to illustrate my invention by two slightly variantforms only,selectin forms which arepractical, efficient and re ativelyinexpensi\-"e, and which at the same time Well illustrate the principlesof my invention.

Figure 1 is a side elevation of a connecter headand its supportingmechanism to which my v,invention is applied.

' Figure 2 is a. verticahlongitudinal section throufrhhe head-consideredas detached from` its supportsshowing one of the forms of my invention.

Figure 3 is asection of,Fignre 2 taken upon line 3 3.

Eigure 4 is a fragmentary longitudinal section lshowing the other form.

The enlargements affordseats for the gaskets 25, 25', Yanchorages for the bolts or studs 2G andab-utments for the outer `ends of. spiral springs-2, surrounding theindividual'l bolts in Figures 2 and B or 27, 28 surrounding theterminals outside and ins'de the1bol`t's, respectively iniigure 4.

he springs press at their rear Aends against the `anges 22 andthe boltsor studs pass `throng thesel annular inwardly directP edjanges 22 andreoeivei lock nuts 29 which bear a. ainst the rear faces of the flanges.

'The eads yare .annular-ly recessedI at 30 to protect the nuts andboltsfrom accidental interference.

The annular recesses 30 Iaffi'ord access for arsocket `Wrench by whichthe nuts may be adjusted. f' The askets'25 and 25 are the usual air pipean steam gaskets, respectively and the steam terminal 'gaskets areretained by the spring 3l as usual. Within the terminals I place ribs 32for engagement by a plug wrench so as to conveniently screw theterminals into the fittings 33, -l for connections which may bel/Vestinghouse and Gold couplers 35 and 36.

My invention is equally applicable to heads intended to carry but asingle terminal, as would more usually be the case in freight serviceand to heads intended to carry two or three terminals as ordinarilyrequired in passenger service.

In assemblage I will consider separately the conditions if the fittings33, 3ft be free to be rotated for application after the rest of thestructure has been assembled and while the terminal is being steadied inits position by a socket wrench.

In that event the studs are first screwed into the enlargements 23 andthe springs are put in position within the spaces 1S. The terminals,with the studs attached, but without the look nuts, and with the springseitherabout the individual studs or about the terminals are put inposition so as to pass the studs through the openings in flanges 22. Thelock nuts 28 are then set and the fittings are subsequently attached.This is the preferred form of assemblage since the capability of placingthe fittings 33, 3st after the head is otherwise assembled, carries withit the capability of disconnection ofthe fittings from the terminalswithout disasseniblage of the rest of the head structure.

Vdiere the fittings are not free to rotate, the springs are insertedwithin the head openings and the terminals are placed and screwed intothe fittings before the studs are placed within the enlargements 23. Thestuds are first passed through the flanges 22 and through or between thesprings and are afterward screwed into the enlargements, after which thenuts 29 are seated by socket or Spanner wrench.

In either event the extent of normal projection of the terminal beyondthe head may be accurately determined and may subsequently be adjustedwith great nicety by seating the lock nuts at appropriate positions uponthe studs.

It will be evident that the main reason for placing the flange 22 withinthe head instead of at the outer edge of the head is to give room forthe nuts within the head and to avoid interference with the adjustmentand breakage of the threaded stems at the rear of the head protectingalso from accidental displacement of these nuts. Where these advantagesof protection do not appeal, there is an obvious advantage in placingtheflange 22 far enough back for the nuts to be accessible by the use of anordin'ary wrench.

" lVhere theisprings encircle the studs or bolts more springs arerequired butthere is some advantage from the increased number ofsprings, in that any one of them is effective to give partial supportand pressure in case of breakage of the others.

It will be obvious that Vthe disclosure of my invention will suggest tothose skilled in the art other forms by which all or a part of thebenefits or" my `invention may Vbe secured, and it is my purpose toinclude herein all such as come within the reasonable spirit and scopeof my invention.
